ABSTRACT:
A sensing element for sensing the concentration of an analyte in a medium is disclosed. The sensing element comprises a matrix material having at least one indicator component covalently bonded thereto. The indicator component is capable of providing a signal dependent on the concentration of a analyte in a medium. The indicator component is derived from at least one indicator compound having an aromatic ring to which is directly bonded a group including a functional portion which is conjugated relative to this aromatic ring.
